This is a long shot, but hoping someone can provide some insight on why I keep popping the fuses on this circuit, it seems to be generally after an IGBT blows. Maybe an idea on circuit protection. The circuit is for ultrsaound cleaning, and cleans well for about 1 minute sometimes. The gate...
im trying to utlize a gate driver to switch two paired mosfets (half bridge) to generate a waveform at 50Khz from -100 to +100 V. The circuit works well to switch positive voltages (0 to 100V). When i add even small negatiuve voltage, ie -5 to +30V, the circuit becomes unstable.
Im not sure...
